User manual M-AUDIO AUDIOPHILE USB

[. . . ] Audiophile USB Owner's Manual version: AP-050103 Table of Contents Introduction . . 33 Introduction Congratulations on your purchase of the Audiophile USB by M-Audio. The Audiophile USB is your audio and MIDI upgrade for any PC or Macintosh computer*, utilizing the convenience of your computer's USB port--no tools or computer disassembly is required. The Audiophile brings you true 24-bit 96kHz audio and the highest-quality stereo, and digital multi-channel surround sound available today. Even if you are experienced in digital recording, please take the time to read this manual. [. . . ] (Or, go to Control Panel | Multimedia | MIDI in Windows 98. ) Set the Audiophile MIDI driver as the default Windows MIDI driver by clicking on the "Out USB Audiophile" entry in the drop-down list, then selecting "OK" or "Apply". Macintosh Sound Manager and the Audiophile USB The Macintosh Sound Manager will allow you to select the Audiophile USB as the system's audio input and output device. Open the Apple menu and select "Sound" from the Control Panels list. However, you may also leave the Sound control panel set to "Built-in" if you wish to use the Audiophile only with your music program and use the internal audio for system sounds. Audiophile USB Inputs & Outputs The Audiophile USB Digital Recording Interface's analog inputs and outputs are compatible with a variety of audio products. The Audiophile USB has both female RCA and female 1/4" TS (tip-sleeve) input jacks, and female RCA output jacks. These jacks allow connection to unbalanced (typically consumer or semi-pro) line level equipment. Only one pair of analog inputs can be used at any given time. When a 1/4" TS plug is connected to the 1/4" line inputs, the corresponding RCA input jack is defeated. If you have RCA cables connected to the Audiophile and then connect 1/4" plugs to the 1/4" jacks, the Audiophile will then get its signal from the 1/4" line inputs. NOTE: In order to preserve its high dynamic range and minimize distortion, the Audiophile USB does not have microphone preamplifiers built into it. Therefore, directly connecting a 13 microphone is not recommended. Instead, pass the microphone signal through a microphone pre-amp (such as the M-Audio TAMPATM, DMP3TM, or Audio BuddyTM), and then connect the pre-amp output to the input of the Audiophile USB. Some additional cable and/or cable adaptors may also be needed to ensure proper connectivity. The Audiophile USB also has digital inputs and outputs in S/PDIF format. These are available on RCA connectors, as stereo pairs. These jacks receive or transmit a digital audio stream that is independent of the analog audio streams. However, because of the bandwidth limits of USB there can be a tradeoff between the number of inputs and outputs that are active and the sampling rate and bit depth of the audio being processed. Also, you should ONLY activate the S/PDIF Input if you are connecting an active digital audio device to this input. This is detailed in the previous section, "The Audiophile USB Control Panel. " Also detailed in the previous section is the use of the S/PDIF Output for sending encoded surround sound signals. Checking the "DD/DTS Pass-Thru" box in the Audiophile USB Control Panel will allow you send Dolby Digital, Dolby Surround, DTS, or any encoded surround sound signal to the S/PDIF Output of the Audiophile USB. You can connect this output to a home theater system, or any device that will decode this signal. Using most DVD players, select the "S/PDIF" option in the DVD players audio setup page, and your computer becomes a high-end home theater player in conjunction with the Audiophile USB. Audiophile USB with Your Music Software Once the Audiophile USB hardware and software drivers are properly installed, the Audiophile is ready for use with your music application software. Some software applications may require you to highlight or enable the Audiophile USB drivers within the program in order to use the Audiophile, while others may have a utility that analyzes or profiles the audio devices in your system and enables the drivers. Your software should have an audio device driver setup page. If you have problems locating it, consult your software's documentation. The Audiophile drivers include MME and WDM drivers for Windows, ASIO drivers for both Windows and Mac, and Sound Manager drivers for Mac. WDM drivers are a more modern driver architecture for Windows operating systems Me, 2000, and XP, but only certain programs like Cakewalk's "Sonar" will take advantage of them. Other Windows programs will automatically access and use the MME drivers. WDM drivers, similar to ASIO, will give you 14 low latency monitoring through the application (check your application's documentation for information regarding input monitoring). If your Windows or Macintosh program is ASIO compliant, like Steinberg's "Cubase" or Emagic's "Logic, " then the program's audio device driver setup page will allow you to select the USB Audiophile ASIO driver. This selection is advised, and described more fully later in this section. Windows MME and WDM Audio Input Devices: Within the setup page of your software application(s), the names of the Audiophile USB audio input devices will be: "M-Audio USB Audiophile Line", and "M-Audio USB Audiophile SPDIF". [. . . ] A Digital Signature Not Found window will appear next Click "Yes. " 31 13. Click "Yes, " again. 14. The driver is now installed in your computer. Next, open the Windows Control Panel and click on the Audiophile USB Control Panel. Select "Place Audiophile Icon in the task bar. " A button which contains a small black "M" and represents the Audiophile USB control panel will now appear in the system tray, for easy control panel access. 32 Windows ME: NOTE: Please make sure the Service Pack 3 is installed.
